I tried a solution suggested by a J de Silva that worked for me. I abbreviated his suggest to #4 which was; Insert XP disk into CD then reboot to Recovery Console, press "R" for recovery, which after password request, just press enter unless you have a password. This will take you to the C:\Windows prompt. Insert "Copy "D" (or whatever is your Cd letter where the XP disc is):\Windows\i386\nfts.sys C:\windows\system32\drivers, then press enter. If the file is corrupted you'll get a message "if should replacefile". Answer Yes, or if there's no message it will install the file. Then remove XP disc, Enter "Exit" and it should reboot clean. Viz; "Copy D:\i386\ntfs.sys C:\Windows\system32\drivers".
